I was able to find a solution with builder: (context,
AsyncSnapshot<documentsnapshot> productSnap)
and final _productMap = productSnap.data!;
it works but i need an explanation please.

In one of my searches on the internet I came across:
The problem here is that by writing Map you are actually writing Map<dynamic, dynamic=""> which will remove important type information. I will recommend just using var or final and let Dart automatically assign the best possible type for the variable:

final _productMap = productSnap.data.data();

but its not working

here is the error: The method 'data' isn't defined for the type 'Object'.
Try correcting the name to the name of an existing method, or defining a method named 'data'.

child: FutureBuilder(
future:
_firebaseServices.productRef.doc(document.id).get(),
builder: (context, productSnap) {
/*Map _productMap = productSnap.data.data();*/
if (productSnap.hasError) {
return Container(
child: Center(
child: Text("${productSnap.error}"),
),
);
}
if (productSnap.connectionState ==
ConnectionState.done) {
Map? _productMap = productSnap.data?.data();

return Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(12.0),
),
//height: 350.0,
margin: EdgeInsets.symmetric(
vertical: 12.0,
horizontal: 24.0,
),
/*child: Text("Nom: ${document['nom']}"),*/
child: Container(
child: Text("${_productMap['nom']}"),
),
);
}
},
),

Sorry sir, I didn't understand your answer. Since I have to translate it first. I'll send you the code with your answer.

Hello sir, I have just tried two solutions but it does not work.
